该电路使用差动电流互感器（或感应线圈）监测流经火线和零线的电流产生的磁场。在正常情况下，这些电流大小相等、方向相反，相互抵消。当发生接地故障时，部分电流泄漏至接地端，产生不平衡。这种不平衡在互感器的次级绕组中产生电压，由集成电路放大和处理。如果检测到的不平衡超过阈值（通常为4-6mA），集成电路会触发继电器或螺线管断开电路，切断电源。

The circuit continuously monitors current flow using a differential current transformer. When it detects an imbalance (ground fault) as small as 4-6 mA, it triggers the integrated circuit to interrupt power within milliseconds, preventing potential shock hazards.
This circuit uses a ferrite core transformer for stable magnetic coupling, high-purity copper wire for efficient current sensing, silicon semiconductor ICs for reliable signal processing, and industrial-grade PCB substrate with lead-free solder for long-term durability in electrical equipment.
The integrated test circuit allows periodic verification of GFCI functionality by simulating a ground fault condition. When activated, it creates a controlled imbalance that should trigger circuit interruption, confirming the system's operational readiness and compliance with safety standards.
